RUBBER MAT.

Specification of Letters Patent. Patented -De 1921 Application filed January 26, 1921. Serial No. $39,984.

T 0 all whom it may concern:

Be it known that I, JEREMIAH KELLEHER, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Rubber Mats, of which the following is a specification.

The mat is designed for use in such positions as the running board of an automobile. \Vhere so placed it must be secured and it is also subjected constantly to changes in the weather. In. carrying out my invention I reinforce the mat with a fabric, this forming a preferable means of reinforcement.

The mat is provided with securing perforations which are reinforced, the fabric reinforcing the rubber sufficiently to make a secure attachment by means extending through the perforations. lVith such mats the mois-- ture which is retained under the mat tends to destroy the mat. One of the features of my invention is the provision of ribs by means of which ventilation is provided below the mat and the mat stiffened.

The invention is illustrated in the accom panying drawings as follows Figure 1 shows a plan view of the mat. Fig. 2 a .vie'w'of the bottom of the mat. Fig. 3 a section on the line 3-3 in Fig. 1. 1 marks the support, as a running board,

'and 2 the mat. The mat is provided with the reinforcing fabric 3, preferably in the form of duck, which is vulcanized in the rubber as the mat is formed. Perforations 4 are also formed in the rubber as it is vulcanized through which means may be extended for securing the mat in place. The mat is provided with the ribs 5 on its upper surface to give it an abrasive action and the ribs 6 are arranged on its under surface preferably crosswise of the mat affording ventilation by means of the spaces 7. I preferably arrange a closing rib 8 along each. edge. This keeps out some of the moisture but does not seal the spaces so as to prevent the drying of the space under the mat.

The ribs further tend to stiffen the mat so that it lies flat on a running board. It is preferable. to arrange the ribs on the upper surface so as to cross theribs on the lower surface, thus stiffening it in both directions.

\Vhat I claim as new is A rubber mat having ribs on its upper and lower surfaces, the ribs on the lower surface being arranged transversely to the ribs on the upper surface.

In testimony whereof I have hereunto set my hand.
